I found a very interesting tidbit in a Washington Post article on RG3.
the Washington Post wrote:
Last winter, Griffin cold-called a training facility he’d heard of near home and, within a week, he walked into the ESPN Wide World of Sports Complex. The facility appealed to Griffin because it had football and a track-and-field program, helmed by coach Brooks Johnson, who also trained Sadeiko. At Baylor, Griffin ran the 400-meter hurdles all the way to the 2008 Olympic Trials semifinals but left track — even though “at heart, I’m a track guy” — to focus on football. He started to consider a comeback.
Griffin split time between the football and track workouts, where he trained alongside Olympians, including Justin Gatlin, who last year outran Usain Bolt for the gold in the 100-meter dash at the world championships. Griffin, who once weighed more than 225 pounds, had slimmed down to 193. He spoke with Johnson about preparing for the decathlon or the 110-meter hurdles.
“He didn’t look at himself as RGIII,” Gatlin said. “He looked at himself as Robert. He was hungry, and he had another a shot to get back out there.”
For about 10 weeks, Griffin arrived at the facility four days per week at 8:30 a.m. and, over the next five hours, stretched, lifted weights, honed footwork and threw to receivers. Whenever workouts called for speed, he sidled over to Johnson.
When asked if track was a plan B, Griffin said he didn’t think so, citing one of his favorite quotes from actor Will Smith: “There’s no reason to have a plan B because it distracts from plan A.”
But the track group watched Griffin chip away at his rusty technique. At first, his body launched wide and splayed over the hurdles, but it quickly became tighter. Griffin is 6-foot-2, but Gatlin said football’s emphasis on low centers of gravity conditioned Griffin to run as if he were 5-foot-2. His short strides generated less power. Slowly, Griffin ran straighter, lengthening his legs. The knee injury that hampered his football career seemed to have no effect. Within a year, Gatlin and Johnson said, Griffin would have seriously contended for a spot at the 2020 Olympic Games in Tokyo.
“He is an Olympic-level talent,” Johnson said. “It didn’t take a lot to get him technically sound.”
Decathlon or 110h? How about the 400h?
